Study Notes

Epithelial Tissue

Stratified squamous epithelium protects against abrasion.
Endothelium is a simple squamous epithelium lining blood vessels and the heart.
Goblet cells provide lubrication within epithelial tissues.
Microvilli increase surface area for enhanced absorption.
Cilia aid in the movement of substances in one direction.

Connective Tissue Characteristics

Extracellular matrix (ECM) of connective tissue comprises cells and fibers.
Types of cartilage are differentiated by the type and arrangement of fibers in the ECM.
Connective tissue forms structural frameworks for organs, including bone, cartilage, ligaments, and tendons.

Muscle Tissue

Smooth muscle is found lining the digestive tract (intestines) and urinary system (bladder).
Skeletal muscle tissue comprises muscles like biceps brachii, deltoid, and pectoralis.

Types of Cartilage

Elastic cartilage contains collagen fibers not visible; retains shape after deformation (e.g. ear cartilage).
Fibrocartilage features chondrocytes lined in rows between collagen fiber bundles, found in intervertebral discs and pubic bones.
Hyaline cartilage has densely packed elastic fibers, located in long bone ends, larynx, costal cartilages, and embryonic skeleton.

Cellular Structures and Functions

Apical surface of epithelial tissue faces the lumen in tubular structures.
Cilia indicate an epithelial function related to moving particles, often found in the reproductive and respiratory tracts.

Connective Tissue Types

Reticular connective tissue forms the inner supporting framework of organs like the spleen, liver, and lymph nodes.
Dense regular connective tissue connects bone to bone and muscle to muscle.
Elastic connective tissue allows structures like the aorta to stretch and return to original shape.
Adipose connective tissue helps retain body warmth and store excess fluid.

Blood as Connective Tissue

Blood is mesodermal in origin, consisting of plasma, erythrocytes, and leukocytes, with fibers present for clotting.

Tumors and Tissue Types

Glioma is a tumor derived from nervous glial cells.
Most tumors arise in rapidly dividing cells, with brain tumors likely originating from glial cells.

Key Comparisons

Cilia propel substances along the apical surface, while microvilli increase surface area for absorption.
Avascularity in cartilage leads to limited regenerative abilities, meaning it won't grow back effectively.
